The establishment of the Trusted Authority has been completed 2 and an official security certification lab appointed.In September 2009 the first batch of 15,000 SMiT (Shenzhen State Micro Technology., Ltd.) CI CAMs was offered by various Dutch retailers, followed in October 2009 by the first batch of Neotion CAMs.If CAM detects that its Host's ID, model or brand is listed in socrl (and isn't listed in optional socwl - Service Operator Certificate White List the CAM must refuse descrambling the content marked in CI URI as protected.The mandatory feature (as it's actually the main raison d'être of CI) is Content Control.Or, module can ask the host to display a message on the TV screen and can then read keypresses from the host remote control.CI.0 edit DVB standards organization announced 5 working on version.0 of the DVB CI specifications.This guts no deposit SAC is used to generate a shared key, unique per a CAM-Host pair, which protects from unauthorized copying the content marked in the associated URI (Usage Rules Info) as a content which needs to be re-encrypted on its way from CAM to Host after.All models produced after early 2011 are fully compatible with.Certification edit CI Host and CAM testing and certification is carried out by Eurofins Digital Testing (formerly Digital TV Labs) in the UK, Hong Kong, Belgium and Poland.Some problems were solved by upgrading the firmware of the TV, other were solved by simply replacing ( in many cases under warranty ) the motherboard.According to the Common Interface scheme: host : A device where module(s) can be connected; for example, an Integrated receiver/decoder (IRD a VCR,.A socrl is created and signed by the CI Root-of-Trust on request of a Service Operator.Module : A small device, not working by itself, designed to run specialized tasks in association with a host; for example, a conditional access sub system, an electronic program guide application module, or to provide resources required by an application but not provided directly.

Embedded Common Interface edit A new etsi working group will be working on Embedded Common Interface (ECI).
The main features added by.3.1 to.2 are: various enhancements of Content Control mechanism coordination of parental control PIN code handling between CAM and its host better IP communication support (increased data throughput) VOD support a new Operator Profile resource allowing CAM.
